Court Rules Limelight Networks(TM) Does Not Infringe Akamai Patent

04/26/2009

TEMPE, Ariz., April 26 /PRNewswire-FirstCall/ -- Limelight Networks, Inc. (Nasdaq: LLNW) today announced that the United States District Court for the District of Massachusetts has granted Limelight's motion for judgment as a matter of law, setting aside a prior jury verdict and ruling that Limelight does not infringe U.S. Patent No. 6,108,703 in Akamai Technologies, Inc., et al. v. Limelight Networks, Inc. (Civil Action No. 06-11109-RWZ).

"We are pleased the Court granted our motion for reconsideration in this matter and ruled in our favor. We have long maintained that we do not infringe the '703 patent," stated Jeff Lunsford, chairman and chief executive officer, Limelight Networks, Inc. "This ruling affirms that Limelight Networks respects the intellectual property of others, and that our growth and success have been achieved through our own innovation, hard work, and customer-focused operations. We look forward to continued collaboration with our customers and partners as we work to enable a global shift in content consumption from closed to open networks, where consumers can enjoy their desired content whenever, wherever and on whatever connected device they choose."

The Company expects this ruling to allow it to reverse expenses of approximately $66 million accrued for potential damages and interest.

The Court's Memorandum and Order, issued on April 24, 2009, cites the standard set forth in the recently decided MuniAuction, Inc. v. Thomson Corp., 532 F.3d 1318 (Fed. Cir. 2008), cert. denied, 2009 WL 578715 (U.S. March 9, 2009) as a key element in deciding to grant Limelight Networks' motion.
